DEFINITION

Classification: 318/107

(under subclass 106) Subject matter in which the sources comprise one or more AC sources and one or more DC sources.

(1) Note. A "pulsating" source is a DC source for purposes of this class. Where, however, a DC source and an AC source are connected to a circuit to produce a pulsating current or voltage in the circuit, classification will be on the basis of plural Sources.
